Real-time biofilm formation of different S. mutans strains in the BHI-sucrose medium (suc) or medium supplemented with 5% xylitol (xyl) or 5% erythritol (ery). aS. mutans NCTC10449 bS. mutans NG8 cS. mutans Ingbritt dS. mutans 2366 eS. mutans 195-s2 fS. mutans 199-s6 gS. mutans 124-s7 hS. mutans 113-s12 iS. mutans 117-s3. Bacteria were let to adhere on E-plate surface for 2 h, after which xylitol was added in the medium. dCI = cell index value change after addition of xylitol, see text for details. Mean ± SD, n = 2–4
